ReadyMADE Seat Collar

ReadyMADE is Tanglefoot's brand of stuff that we found in a Taiwanese catalog, ordered, tested, and found up to snuff.  We didn't design it, but we trust it, and it's a great product for the ducats. 

The ReadyMADE seat binder that needs relatively low torque (compared to say, a Surly or Phil Wood clamp) to really put your seatpost on lock.  That makes it good for lighter seatposts and dropper posts.  Fun colors.  Non-proprietary bolt, so if you strip it, you can easily replace it.  

Two sizes:  Get the 29.8mm clamp for 29.8 to 30mm seat tubes, aka most steel bikes that take a 27.2 seatpost.  Think: Tanglefoot. Or get the 33.1mm.

These match the ReadyMADE headset spacers and Rollcii Headsets.
